Progression Quotes

A large number of well-trained scientists outside of evolutionary biology and paleontology have unfortunately gotten the idea that the fossil record is far more Darwinian than it is. This probably comes from the oversimplification inevitable in secondary sources: low-level textbooks semipopular articles, and so on. Also, there is probably some wishful thinking involved. In the years after Darwin, his advocates hoped to find predictable progressions. In general. these have not been found-yet the optimism has died hard and some pure fantasy has crept into textbooks.

David M. Raup
As there must be moderation in other things, so there must be moderation in self-criticism. Perpetual contemplation of our own actions produces a morbid consciousness, quite unlike that normal consciousness accompanying right actions spontaneously done; and from a state of unstable equilibrium long maintained by effort, there is apt to be a fall towards stable equilibrium, in which the primitive nature reasserts itself. Retrogression rather than progression may hence result.
